FRANK 13,131.51', OF WABASH, INDIANA- GLUING CLAMP AND DRIER.

Application led October 13, 1919. Serial No. 330,272.

To @Nw/10m it may concern Be it known that I, FRANK DIEHL, a citi.- zenof the United States, residing at lslilabash,` in the county of Wabashand-State of Indiana, have invented a new and useful (Jrluing Clamp andDrier, of which the fole lowing is a specification.

This invention has reference to the class of wood working, moreparticularly to an improved gluing clamp and drier.

The object of the invention is to provide an improved form of housingand heating means for a revolving` clamping machine by which boards orsections of wood may be effectively clamped together at their gluededges and the device being so provided that heat radiating over theclamping device will be diffused'to such an extent to evap orate waterfrom the glued joints of the boards or sections of wood being glued together, thereby permitting the glue in the jQint to be dried quickly andpreventing the water in the glue from swelling the wood and causinggreat loss due to the `opening of the joint by shrinkage after having`been swelled by the water and moisture.

With the above and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that, within the scope ofwhat is claimed, changes in the precise embodiment of the inventionshown can be made Without departing from the spirit of the invention.

In the accompanying drawings:

Figure 1 is a plan view of the device constructed in accordance with myinvention, the housing means being removed;

- Figure 2 is a plan view of the complete device;

Figure 3 is an enlarged vertical sectional view therethrough.

Referring to the drawings in detail, in which similar referencecharacters designate like parts throughout the several views, thenumeral 10 designates the end bearings of a revolving clamp upon theupper ends of which is horizontally journaled a shaft 11. Mounted uponthis shaft are circular end castings 12 preferably having concentricrings to which are connected in any suitable manner, a series oftransversely spaced clamps including arms 13 for supporting the boardsor sections of wood thereon in radially extending relation between theclamping members 14.

There is also disposed at the front of the l machine on the floor line15 a rocking beam 16 which normally extends into the path of onel of thearms 13. This beam is adapted to swing downward on ahorizontal pivot A17at the floor in order to release the arm 13 and the clamps thereon so asto allow the clamping machine to revolve downward.

This rocking means is shown extended upwai-diy and outwardly and adaptedto be actuated by foot pedals 18.

1n accordance with the presentinvention, the Vclamping machine is partlyor entirely inclosed and has arranged therebeneath vor steam pipes 21,althoughy it is to be unf derstood that said pipes are adapted to carryany other suitable heating medium but are especially arranged in aninclined position, so as to prevent any condensation or water fromlodging in the pipes.

Enveloping the clamping and gluing machine, is a housing comprising afront wall 22 having an opening 23 through which the clamps areaccessible for placing and removing the boards or the like to beclamped. The housing also includes a top portion 24 and a back or rearportion 25, which may continue below the floor 15 which said Hoor is cutout as shown at 26, in order to permit the heat to radiate from theheating means consisting of the coil arranged with one end hic-her thanthe other for the purposes heretofore stated. As shown the heat pipes orcoils are preferably arranged in a forwardly inclined position at therear of the machine, this heating means causing a diffusion of the heatin the inside of the machine within the housing, for purpose ofradiating heat all over the clamp to such an extent as to evaporate thewater from the glue in the joints ofthe table tops, chair seats and allsimilar work where two ieces of wood are glued together. The resu t isthat 'the mater being evaporated jfrom the glue, causes the glue to dry1n the `ioints very quickly and prevents the water in the glue fromswelling the wood and causing great loss7 as often happens at thepresent t1me by reason of the method o'f gluing in vogue, since theswelling" ot' thewood by the moisture and then the shrinking thereof,makes depressions along the wood at the joints where the pieces of woodare glued together. rlhese objections are entirely overcome by thepresent device.

The rocking beam or .structure 16 has a curtain 28 attached to it andformed of canvas or the like, this curtain serving to close the lowerportion of the opening in the housing. The curtain is adapted to swingoutward with the beam 16 when said beam is shifted to release the armsof the clamps. lWhen one of the arms 13 is resting on the beam 16 it issupported in position to give ready access to the clamp on said arm,thus to allow wood sections to be placed easily between the members olthe clamp and to be readily removed.

This drying arrangement is a very valuable feature in furniture andmanufacturing of all kinds as well as chair and casket parent that thewater in the glue will be so quickly dried that swelling and shrinkingof the joints will be prevented, thereby preventing loss of materialincident to the causes mentioned.

In Figure 1 of the drawings the device is shown also with the housingremoved, the heating means or coil 21 being shown in elevation. InFigure 2 of the drawings, the housing is indicated and at one end of thehousing, there is shown a blow fan 29 adapted to force air through thehousing so as to assist in the drying operation. The exit is madethrough an outlet 30, which may be provided with asui'table suction Jfan81 il desired and an adjacent operating table 32.

Having thus fully described the invention what vis claimed is:

rThe combination with a housing having an opening in one wall, ot a stopmember mounted to swing within the opening, a curA tain suspendedtherefrom for closing a portion of the opening, a series of radial clampcarrying arms mounted for rotation in the housing and movablesuccessively toposition upon the stop member to limit the rotation ot'the arms, and heating means'within the lower portion ot the housing andclose to the path of the arms. Y

In testimony that I claim the foregoing as my own, I have hereto afiiXedmy signature in the presence ot two witnesses.
